Strange behavior of check_http

[Francois JEANMOUGIN]

Hi all,

I used check_http succefully for months now and found a strange behavior :

If you use:

check_http -H yourhost.yourcompany.com -I 1.2.3.4 -f follow -U /test.htm -w 4 -c 6

You expect it to :
- connect to 1.2.3.4 port 80
- send :
GET /test.html HTTP/1.0
Host:yourhost.yourcompany.com

This is usually the case. But if youhost.yourcompany.com is defined in /etc/hosts (say, with another IP like 1.2.3.100), then, this will override the -I option... The application will connect to 1.2.3.100 instead of the 1.2.3.4 defined in the command line option.

Is it a bug or a feature? I had a look at the check_http.c code, and have to confess that I didn't find the reason of it. Any idea from the devs ?

François.
